A jiffy clock for the Apple IIc,II+, and IIe with a mouse

A “jiffy clock” is presented for the Apple lIc or other Apple II having Apple’s mouse card. The clock allows timing of events to tenths of a second, and is read from BASIC. A convenient elapsed timer function is provided as well.     

Screen blanking on the Apple IIe

Screen blanking on the Apple IIe can be controlled by software after an annunciator output is connected to the chip enable line (Pin 18) of the character generator (UF4). Using Annunciator 3 gives the same functional results with the Apple IIe as does Reed’s (1979) hardware modification for the Apple II and Apple II+.     

Parallel processing strategies in the application of microcomputers to the behavioral laboratory

The Operant Package for the Neurosciences (OPN) is a software system that runs on the TRS-80 Model I and Model III and the Apple II+ and Apple lie microcomputers. It is designed to allow a single microcomputer to control behavioral experiments in up to eight different stations, record experimental data, and provide detailed data analysis. Although segments of the program are written in BASIC, allowing users to interact with OPN in a simple English question-and-answer format, the part that provides real-time experimental control is written in Z-80 assembly language. The present report describes in detail assembly language algorithms that we found to facilitate speed of processing and flexibility of control. Particular problems dealt with how to update and change flag variables controlling the reinforcement contingencies and output conditions in each station, as well as how to decide when each station should shift contingencies. The solutions to these problems utilize byte-oriented parallel processing strategies, converting serially organized reference information for each station into a group of working flag bytes that control contingency and output variables for all stations in parallel.     

Dyadic Mental State Talk and Sophistication of Symbolic Play between Parents and Children with Behavioral Problems

Parents’ ability to recognize children’s mental states and use mental state language in their interactions are associated with children’s mentalization, affect regulation, and symbolization in play. However, the relations among these constructs have not been investigated in school-age children with behavioral problems. This study examined the association between 53 Turkish mother-child and 40 father-child dyads’ mental state talk, children’s play characteristics, and behavioral problems at the beginning of psychotherapy. Results indicated that parents’ and children’s play-related mental state talk was associated with children’s interactive role-play, and mothers’ mental state talk was associated with children’s affect regulation in play. Moreover, mental state talk through pretend play was linked with fewer internalizing symptoms; yet a direct focus on children’s mental states out-of-pretend play was correlated with more behavioral problems, highlighting the multidimensional nature of the mentalization construct. These results are discussed taking into account the socio-cultural variations of the Turkish culture highlighting the unique characteristics of the parent-child play in context. The clinical implications point to the importance of parental and child mentalization within pretend play, that provide opportunities for affect processing, which could promote symptomatic improvement.     

Maternal Mind-Mindedness and Children’s Behavioral Difficulties: Mitigating the Impact of Low Socioeconomic Status

Relations between mothers’ tendency to comment appropriately on their 8-month-olds’ internal states (mind-mindedness) and children’s behavioral difficulties (Strengths and Difficulties Questionnaire) at ages 44 and 61 months were investigated in a socially diverse sample (N?=?171, 88 boys). Controlling for maternal depressive symptoms, perceived social support, sensitivity, child language ability, and child gender, maternal mind-mindedness was negatively related to children’s externalizing and internalizing behaviors specifically in low socioeconomic status (SES) families. Furthermore, behavioral difficulties at age 44 months mediated the relation between maternal mind-mindedness and behavioral difficulties at age 61 months, but only for low SES families. These findings are discussed with reference to possible ways in which mind-mindedness could inform interventions targeted at at-risk groups.     

Examining the Efficacy of Online Administration of a Time-Limited School Readiness Intervention in the Face of COVID-19

Although the efficacy of online administration of behavioral parent training (BPT) programs is well-established, such programs address a single risk factor (behavioral functioning) for school readiness difficulties (comprised of academics, cognitive skills, and social, emotional, and behavioral functioning). The current study aims to examine the feasibility, acceptability, and efficacy of a telemedicine delivery of the School Readiness Parenting Program (SRPP), an integrative adaptation of PCIT designed to address the behavioral and academic domains of school readiness. The present study takes the first step towards validating an online administration of the SRPP as a treatment for early childhood disruptive behavior. Data were collected for 64 children ages 2–6 years (M^age = 4.63, SD = 0.86; 78.1% Hispanic/Latinx) and their families, who received either in-person administration of time-limited PCIT (PCIT-TL; n=30) or online administration of SRPP (n=34). A series of repeated measures ANOVAS were conducted to examine within and between group effects. Results revealed that both SRPP and PCIT-TL significantly reduced inattention (d’s = −0.54 to −0.88), aggression (d’s = −0.55 to −1.06), and behavioral symptomology (d’s = −0.55 to −0.85) and produced significant gains in parental skills (d’s = −1.47 to 2.99). Notably, online SRPP demonstrated greater improvement in positive parental verbalization, whereas PCIT-TL demonstrated greater reductions in parental stress. Overall, findings support the utility of online SRPP for addressing behavioral school readiness concerns.     

Apple II assembly language routines for digital data acquisition and contingency control

Modifications and corrections to Rayfield’s (1982) assembly language routines for data acquisition and experimental control using the Apple II computer are described. The modified routines, together with an optoisolated hardware interface, provide a reliable, accurate, and easy to use microcomputer system for experimental control and data acquisition.     

On-line Apple II for the recording and analysis of complex motor movements

The system described here was prompted by the need for a method of separately recording various components of a complex motor act. The task involved vertical, horizontal, and turn components. Our particular interest was the relation between integration of components and level of skill demonstrated. The peripheral equipment provides a separate analogue output for each component and plugs directly into the Apple’s game-paddle input. Trial data are stored directly on disk and can be retrieved for subsequent graphical plotting and analysis. The Apple II accommodates up to four inputs and returns results for movements as fast as .05 sec. The programming system can be used, without modification, for a wide variety of motor tasks. No additional interface or clock is required.     

Individual arousal-related performance zones effect on temporal and behavioral patterns in golf routines

AimConsistency, both in duration and behavior, of pre-performance routines has been closely related to overall performance quality. However, recent findings highlight that psychological and physiological states may have important implications for routine consistency. To further clarify this relationship, the present study sought to examine changes in routine consistency with respect to optimal and non-optimal arousal states.MethodThe present case study observed the performance routines of three high-skilled golfers during three rounds of competitive golf. Measures of arousal (heart rate) and outcome performance were used to determine each golfer’s Individual Arousal-related Performance Zones (IAPZs) (Kamata, Hanin, & Tenenbaum, 2002). Subsequently, temporal and behavioral patterns (consistency and number of rehearsal swings and glances toward the target) for both the full swing and golf putt were assessed across poor, moderate, and optimal levels of the golfer’s IAPZ.ResultsIdiosyncratic differences in routine patterns, both behaviorally and temporally were evident. More importantly, the consistency of the routines for each golfer varied under different arousal-related performance zones. That is, the temporal and behavioral patterns of the golfers varied in idiosyncratic ways across the IAPZ levels.ConclusionsThese findings suggest that factors that influence a performer’s arousal level can lead to idiosyncratic variations in a performer’s routine. Observation of these routine changes can provide insight into the negative tendencies that an athlete can have when performing outside their optimal zone. With this knowledge, practitioners can be more effective in helping athletes monitor and regulate arousal, which will ultimately lead to enhanced performance.     

Assessing the impact of a family nurse-led intervention on young mothers’ references to internal states

A mother's propensity to refer to internal states during mother–child interactions is important for her child's developing social understanding. However, adolescent mothers are less likely to reference internal states when interacting with their children. We investigated whether young mothers’ references to internal states are promoted by the Family Nurse Partnership (FNP) intervention, an intensive home-visiting programme designed to support adolescent mothers in England. We also investigated family, maternal, and child factors associated with young mothers’ references to inner states during interactions with their children. Adolescent mothers (n = 483, aged ≤ 19 years when recruited in pregnancy) and their children participated in an observational substudy of a randomized controlled trial investigating the impact of FNP compared to usual care. Mother–child dyads were video-recorded during free play, and mothers’ speech was coded for use of internal state language (references to cognitions, desires, emotions, intentions, preferences, physiology, and perception). We found no differences in mothers’ use of internal state language between the FNP and usual care groups. A sample-wide investigation identified that other features of mothers’ language and relationship status with the child's father were associated with internal state language use. Findings are discussed with reference to targeted interventions and implications for future research.     

Multilevel and Cross-Level Effects of Neighborhood and Family Influences on Children’s Behavioral Outcomes in Trinidad and Tobago: The Intervening Role of Parental Control

The objective of this investigation was to examine the associations among neighborhood conditions, neighborhood collective efficacy, family economic disadvantage, parental control behaviors, and children’s behavioral outcomes using multilevel and cross-level analyses. The proposed conceptual model incorporated propositions advanced by social disorganization theory, the structural-process model, as well as the Family Stress Model. Data were collected from a nationally representative sample of 1,337 families with children between 3 and 6 years (668 boys) drawn from 45 communities in Trinidad and Tobago. Neighborhood level indicators were assessed using census as well as parent reports whereas individual level constructs were assessed using parent reports. Findings indicated support for the Family Stress Model in that harsh punishment and parental monitoring functioned as mediators of the relationship between family economic disadvantage and behavioral difficulties (parental monitoring for prosocial behaviors). Findings from the multilevel analyses indicated that the relationship between neighborhood infrastructure deprivation and children’s behavioral difficulties and prosocial behaviors was mediated through neighborhood collective efficacy and parental harsh punishment. Cross-level interactions indicated that neighborhood collective efficacy buffered the relationship between parental discipline, monitoring, harsh discipline and behavioral difficulties. Given the importance of communities and families in influencing children’s behavioral outcomes, due consideration must be given to utilizing multilevel and cross-level perspectives both in research as well as in the development of intervention programs. Policies and programs designed to improve neighborhoods conditions, promote neighborhood collective efficacy, and advance the socioeconomic opportunities for families can help enhance the well-being of children.     

A microcomputer package for real-time skin conductance response analysis

A suite of programs has been developed to acquire data from a commercially available, highquality skin conductance meter, via a standard IEEE bus, on an Apple II or Apple lie microcomputer. These programs score and analyze stimulus-evoked skin conductance responses in a preset time window, and store the resultant data on disk, if required. Facilities for a manual override of the automatic scoring routine are available. The setup offers a method of scoring data as they are acquired; it uses currently recommended standards for skin conductance analysis and allows a high magnification of responses, without any need for continual monitoring, because of hardware facilities that automatically “back-off” a subject’s tonic skin conductance level.     

Do Children Behave Better When Parents’ Emotion Coaching Practices are Stimulated? A Micro-Trial Study

The links between parents’ emotion regulation practices and children’s behavioral outcomes are well established. The aim of the current study designed as a randomized micro-trial was to test experimentally if and to what extent stimulating parents’ emotion coaching practices improves preschoolers’ behavioral outcomes, i.e. positive affect, irritability, non-compliance, persistence and enthusiasm. In line with this objective, the emotion coaching practices of parents of 4-to-5-year-old children were stimulated in a brief 15-min lab session. Immediately afterwards, parents and children were observed during a free-play session and frustration laboratory tasks designed to elicit negative emotions in children. The results indicated that, compared to the control group, parents whose emotion coaching practices had been stimulated displayed higher positive affect and were more emotionally sensitive during free play. Positive behaviors persisted in frustration tasks; parents were more behaviorally and emotionally responsive towards their children. In turn, children of these parents displayed higher persistence and enthusiasm but only when they had to deal with negative emotional arousal during frustration tasks. Mediation analyses also confirmed that the influence of the stimulation of parents’ emotion coaching practices on children’s outcomes, i.e. persistence and enthusiasm, was mediated by the parents’ behavior.     

A Brief Report on the Assessment of Distress Tolerance: Are We Measuring the Same Construct?

Distress tolerance (DT) refers to an individual’s capacity to cope with aversive internal (e.g., physical, cognitive, emotional) states. A growing body of evidence suggests that there is a relationship between DT and the development and maintenance of problematic behavioral patterns. Despite emerging evidence for such associations, a number of issues remain unresolved. The results of recent studies suggest problems with the convergent validity of the primary measures used to assess DT, despite the fact that these measures are used interchangeably in the DT literature. In order to further examine the relationships among DT assessments, we evaluated intercorrelations among various self-report and behavioral measures of DT in an unselected undergraduate sample (n = 83). Results indicate that two self-report measures of DT were highly correlated with one another, but that neither measure was significantly correlated with the behavioral measures. The relationships among the behavioral measures and between self-report and behavioral measures were weak and non-significant. Correlations between self-report measures only were strong. The findings partially replicate prior research indicating weak correlations between certain, commonly used measures of DT, and raise questions about the current conceptualization of the construct.

Millisecond timing on the Apple Macintosh: Updating Drexel’s MilliTimer

In 1986, we published inBehavior Research Methods, Instruments, & Computers a small library of assembler code for the public domain that permitted accurate millisecond timing for Apple’s Macintosh computer. That version of MilliTimer used the Versatile Interface Adapter chip’s Timer 1 (VIA T1), which is part of the standard Macintosh hardware configuration. The VIA T1, however, is also used by the Sound Manager, and thus the use of sound and accurate millisecond timing were incompatible. We offer for the public domain a new version labeled MilliTimer 2.2, which permits psychologists and other researchers to use the full capabilities of the Macintosh. MilliTimer 2.2 is compatible with popular teaching, research, and clinical tools such as Hyper-Card and MacLaboratory. MilliTimer 2.2 employs the Macintosh Time Manager, which is a part of the Macintosh operating system and is supported by Apple for the 512KE, Plus, SE, and Macintosh II machines. MilliTimer 2.2 is hardware-independent and automatically self-corrects for other operating system activities that also use the Time Manager. The self-correcting function is limited, however, and can result in a nonaccumulating error averaging about ?3 msec. To preserve compatibility with earlier machines that do not contain the Time Manager, a simple mode parameter allows MilliTimer 2.2 to use the older, more accurate timing method.     

Optical and electronic systems for spatial and temporal analysis of video images

In this paper are described two systems for spatial (two-dimensional coordinates) and temporal analysis of video images. In the optical version, the Apple IIe generates a pointer on an Apple monitor; the pointer is then superimposed on the video image of a second video monitor, by reflecting the pointer with a half-silvered mirror. In the electronic version, a special card was designed for the Apple IIe to generate a pointer directly on the other video monitor. Both systems use the same software. The procedures of spatial and temporal data acquisition and storage are described as well as the reading, writing, printing, removing, listing, chaining, and dating operations of the digital and graphics files.
